Comparison of 3 protocols for analgesia control after cesarean delivery: a randomized controlled trial.

Background: Proper pain control after cesarean delivery is of high clinical importance to the recovery and relief of patients after surgical delivery.

Objective: We aimed to compare fixed time interval to on-demand regimens of nonopioid analgesics and to assess whether a protocol that is based on intravenous administration is superior to oral administration.

Study Design: This was a randomized controlled trial performed between April 2017 and May 2018.
